CIBCULATIIQ'G-FITTING.

Specification of Letters Patent.

To all whom it may concern:

Be it known that 1, WILLIAM A. BODELL, a citizen of the United States, and resident of Bluefield, in the county of Mercer and State of West Virginia, have invented certain new and useful Improvements in Circulating- Fittings, of which the following is a speclfication.

This invention relates to a single fitting embodying both circulating connections for radiators in heating systems, and while especially adapted for use in connection with hot water heating systems, it may also be used to advantage in steam heating systems. The primary object of the invention is to produce a fitting of this character that will be cheap to manufacture, simple in construction, yet efiicient in performing its 1ntended use.

Another object of the invention is to produce a circulating fitting which can be connected at one end directly with the conventional type of radiators and connected at the ence to the illustrative embodiment shown in the accompanying drawing.

In said drawing :Figure 1 is a side elevation partly in section of a radiator with the device applied and connected to the flow and return pipes of the system; Fig. 2 is a plan view of the device; Fig. 3 is an end.

view of the device looking from that end which is connected to the radiator. and Fig. 4 is an end view of the device looking from that end which is connected to the flow and return pipes of the system.

Referring to the drawings in detail, A represents the radiator which is provided with the usual circulating sections, which sections are usually connected at their top and bottom by suitable top and bottom chan' nels.

which embodies a cylindrical casing subdivided by means of a longitudinal diaphragm 2, which is turned up at the outer end of the casing to provide a bafile plate .3. The cylindrical casing is further provided with intake and outlet legs'4 and 5, which legs extend outwardly therefrom and are disposed in such a manner as to present their ends on different horizontal and vertical planes relative to each other. With these legs 4 and 5 thus disposed, one of them, namely, the leg 4, provides an intake which is adapted to be connected to a suitable controll g valve 6 which in turn is connected to the flow pipe 7 of the system, and the leg 5 provides an outlet for connection to the return flow pipe'8 of the circulating system.

When the device is applied to the radiator, the parts are adapted to assume positions as shown in Fig. 1, in which the cylindrical casing is screw threaded into the radiator until a suitable collar 9 thereon abuts the casing permits connection with circulating pipes presented in line.with the end of the radiator, it will also be seen that by reason of the legs 4 and 5 being disposed on opposite sides of the horizontal axial plane of the casing they maybe connected.-

with equal facility to circulating pipes presented at the back line of the radiator, it

being merely necessary in making such a connection to use the stock nipples and Us ordinarily used to connect radiators to their pipes so located. Of course, the fitting may be used in positions other than with its radially presented inner opening vertical, and in fact, in any position where the two channels to be communicated with are respectively radial and axial to the fitting. Hence the salient characteristics of the placing of the two outer connecting. legs are that they are presented in the direction of the axis of the casing, and on opposite sides of two axial planes of said casing, that are perpendicular to each other.

I claim I 1. A single piece fitting for both supply and return connections in radiators, comprising a cylindrical casing divided interiorly into two longitudinal passages having their inner ends presented n .difl'erent directions; said fitting having at its outer end a pair of connecting legs with ends adapted to receive supply and return connections,

said ends being presented in the direction of Jthe axis of the casing and lying on opposite sides of two axial planes of the casing that are perpendicular toeach other.

2. An integral internally-partitioned, douible-pa ssage fitting for both supply and return connections in radiators comprising a casing fitted to an external opening of the radiator, with its passages communicating with the circulatinggand return channels of the radiator, respectively, and a pair of connecting legs projecting from the casing in line with but on opposite sides of the horizontal and vertical planes of its axis, and

connected respectively to the supply and return pipes of the system. r

V 3. A single piece fitting for both supply and return connections in radiators, comprising a cylindrical casing divided interiorly into two longitudinal passages byan internal partition, said partition having an upturned portion at its outer end adapted, to abut against the end of one of the radiator sections to intercept communication between the passages and present their inner ends in different directions; said fitting having at its outer end a pair of connecting legs with ends adapted to, receive supply and return connections, said ends being presented in the direction of the axes of the casing and lying on opposite sides of two axial planes of the casing that are perpendicular to each other.
